ONTOGENy OF THE FORM OF LIVING BEINGS<br />

Abstract: The form of living beings has its origin in the<br />

temporal dimensions of ontogeny and phylogeny and is the<br />

result of <strong>de</strong>terministic and regulative strategies. In animal<br />

ontogeny, form is initially expressed in the cells, which work<br />

as primary morphogenetic units or form building blocks, and<br />

it is then transmitted from them to more complex levels of<br />

biological organization such as tissue and organs, to finally<br />

mold the entire organism. The generation of form <strong>de</strong>pends<br />

not only on the action of genes and their interaction with the<br />

environment, but is also governed by the general principles<br />

of physics and mathematics, an i<strong>de</strong>a inspired by the legacy<br />

of Sir D’Arcy Wentworth Thompson in his book entitled On<br />

Growth and Form (1917).<br />

Keywords: form, morphogenesis, biology, ontogeny.<br />
